GLASS-MELTING FU RNACE.

SPECIFICATION forming part of Letters Patent No. 376,029, dated January 3, 1888.

Application ined .Iuiy 29, ieee. seri-ai Nanna-184. (No model.)

To @ZZ whom it may concern:

Beit known that LHENRY DULIRE,aformer subject ofthe King ofBelgium, havingresided for more than one year in the United States,and

having made oath of my intention of becoming a citizen of the United States, now residing in Meadville, in the county of Crawford and State of Pennsylvania, have invented an Improvement in Glass-lyIeltingFurnaces, of which Io the following is a specification.

My :invention relates to that class of glassmelting furnaces'where pots are arranged in rows on each side of the chamber, with a gloryhole to each pot and spaces between the rows I5 lto withdraw or replace any pot when necessary.

The object of my invention is to convert the slack of coal'into gas and carry it from the producers in a heated state to the melting- 2c chamber, at the entrance of which, combined with heated air, I effect a more perfect combustion, and by introducing the gas at different points of elevation at the ends of the chamber I obtain an equaldistribution of ii-ame,and

23 by discharging it near the door I get the full benefit of the heat. I attain t-hese objects by the structure illustrated in the accompanying drawings, in which- Figure I is a vertical transverse section 3o near the middle. Fig. 2 is a horizontal section cut at a point just beneath the ioor of the'melting-chamber, as seen from above. Fig. 3 shows the furnace in perspective.-

Similar letters refer to similar partsin the several views.

I construct my furnace with four producers, two at each end, with a passage-way at each end between them, and the gas, as fast as generated, rises through the central flue, F, and the 4o side lues, G. F enters the melting-chamber centrally near the door and is supplied with air for combustion through a duct, I, passing under F, through the heated chamber between the two ovens, and the fines G G lead from 4 5 the arch of the ovens,through the walls A A, up to the top of the chamber,where it is met by air-ducts H H, (shown by dotted lines, see arrows,) which air-ducts,entering the walls on the sides of the ovens, are continued round 5o through the walls of the chamber till the heated air and the hot gas unite, (see G H, Fig. l.) There are two jets,G G, and one jet, F, at each end of the chamber. The mains K K at each side of the chamber reach from wall to wall near the door and have an opening at each pot through which the draft is madeinto the chimney L, (see-arrows s s, Fig. 2.) Oentrally under the chamber I construct a cokeburner, M, whose heat is carried directly up to the long recess N, constructed in the floor of the chamber to give additional heat when required. v

The fuel to the gas-ovens is supplied from the top,through .I .I ,to the grate-bars-E E.

B B are arches of gas-producers. 6'

. The side elevation in perspective shows the glory-holes T T, the inspection-holes V V, to

be closed with fire-clay plugs, and the door W for the lintroduction and removal of pots.

D is the top of chamber-arch.

There are slide-gatesX X to each gas-tube, whether F or G, to regulate or shut ofI" the flow, in easy reach from the outside.

When natural gas is used in this meltingchamber,I close up the ovens below and puta tube in each oven and coke-burner M, and regulate its consumption precisely as I do the artificial gas.

N is a chamber made in the door of the melting-chamber, so as to receive the products of combustion from the coke-burner M. The heat is readily transmitted through the metallic Hoor to the space above,while the products of combustiomafter parting with the larger part of the caloric, find their way to the smolre- 8 5 stack. By this arrangement of distributing the gas-openings into the melting-chamber from both top and bottom I geta more regular heat throughout, and by discharging the flame into the chimneys in the end walls I still further economize heat.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a glass-melting furnace, the combination, with the meltinglchamberand producers, of the fines F, leading from the top of the arches of the combustion-chamber and entering the melting-chamber centrally near the floor, the side lines, G, leading from the combuStion-chamber through the wallsto the upper roo part Of the melting-chamber, and the :Lird nets H. I, carried through the Walls and between Il ranged Coke-burner Openingiuto the chamber the ovens to heat the air, u s and for the pur- 'l of said floor, as und for the purpose set; forth.

. T l* pose Set forth I HEB RY DULLRE.

2. In a g1ass-1nelting furnace, the combination Ofu melting-Chamber, a hollow ehambered metallic floor thereunder, and u centrally-un Vibnesses:
